Penetration of Episode 3:
In the autumn of 1945, the PLA troops were ordered to go to the northeast, and Xu Zhongyi was ordered to enter the military unified spy organization in Shenyang. Chen Ming, the head of Shenyang secret service, is deeply suspicious of Xu Zhongyi who suddenly escaped back. Xu Zhongyi defuses Chen Ming's various tests and investigations.
With the cooperation of the Soviet Army guarding the warehouse, Xu Zhongyi not only made Chen Ming taste the sweetness, but also secretly transferred most of the goods to our army. Because Chen Ming had the eyes and ears of Mr. Qi, who was far away in Chongqing, soon learned about it.
Yang Kecheng designated Mr. Meng of Siji barber shop in Shenyang as Xu Zhongyi's contact person. Yang Kecheng told Xu Zhongyi that the little girl would take part in underground work in Shenyang.
